Angry Birds 2 has flown to the top of the download charts on iOS and Android, hitting 20 million downloads in its first week of release.



According to Rovio's creative director Patrick Liu, it took nine months for the first Angry Birds game to reach as many players - something helped along by the fact that Angry Birds 2 eschews the original's paid app model in favour of free-to-play.

Rovio adds that over 1.4 billion hapless birds have been launched in Angry Birds 2 so far, with over 300 million levels cleared.

This first full Angry Birds sequel was announced last month.
